Rotterode #2 / Koppenstein Thundereggs

A rare German location and surprisingly different to the Rotterode bed #1. There is plainly a distinct change in the geology here since we are observing a very distinct split between the Gehlberg-like thundereggs (#1) and the Brand-like thunderegg (this #2). These have sometimes been called Koppenstein thundereggs as well - both names seem to be used.

The #2 stones are characterized by solid agate cores, actually relatively unusual for thuringia, within a richly purple granular matrix. As one would expect, that agate is deeply flawed, but the colour scheme and the rich sense of depth within these rocks makes them quite compelling, in my opinion.
